Q9. I am new to skiing. What should I be careful about?
1, Arriving Early at SNOVA
For first-time skiers, the preparation required
before you start skiing typically takes longer than expected.
Please arrive at least 30 minutes before your lesson, and 45 minutes
before on weekends and holidays.
Lessons on the slope will begin as soon as you are fully prepared.
Preparation includes:
① Putting
on and taking off ski boots and ski wear:
Ski boots are made of hard plastic and require some knowledge, tips,
and practice to put on correctly. I will help you with this process.
② Handling
ski equipment (skis and poles):
These are specialized tools that you do not use in everyday life.
Knowledge and simple techniques are needed
to carry, attach, detach, and handle them safely.
I will assist you with these steps.
2. Choosing Ski Boots, Socks, Skis, and Poles
①Ski boots:
Ski boots are designed to transfer your body’s power
and movements directly and efficiently to the skis.
The boot size must match your actual foot size for a proper fit.
If your foot moves around inside the boot,
you will not be able to control your skis.
The correct boot should feel snug overall
—this is different from normal shoes,
which are usually larger than your actual foot size.
Even intermediate skiers often misunderstand this point.
②Socks：
Socks should be long enough to cover your shins
to prevent rubbing between the boot and your leg.
Socks that are too thick reduce boot fit;
socks that are too thin may cause cold feet.
Rental socks are not prepared at SNOVA. You need to bring them on
your own.
③Skis:
For first-time skiers, choosing skis that are too long makes them difficult
to control and often leads to fatigue and disappointment.
I recommend shorter skis, 20cm shorter than your height.
④Poles:
Poles are used during my lessons.
Proper use helps with attaching/detaching skis, moving on snow,
and preventing unnecessary falls, giving beginners a sense of security.
The appropriate pole length is approximately your height × 0.67.
However, poles must never be used as brakes while skiing
— this is dangerous.
Details will be explained during the lesson.
3. Ski Wear and Related Gear
①Temperature and required gear:
The temperature on the SNOVA slope is around 0°C,
ｓo proper protection against the cold is necessary.
Ski wear, a helmet, and gloves are required, and these can be rented
at SNOVA.
Sunglasses are not needed.
②Underlayers:
You do not need to wear thick clothing under your ski wear.
First-time skiers spend time walking on the snow, turning around,
and climbing small slopes.
This involves considerable physical movement, and it is common to sweat.
Bringing a change of underwear is recommended.
4. Preparing in Advance
①If you are skiing for the first time, it is essential to keep the skis
in a wedge (V-shaped) position.
To do this, you need to rotate both thighs inward and
continuously open the heels while pivoting from the
toes.
Maintaining this posture requires flexibility in
the muscles
along the back of the lower body
(the gluteal muscles, hamstrings, calves, Achilles
tendons, etc.),
as well as activation of the inner thigh (adductor)
muscles.
②If you have normal physical ability,
there is generally no need for excessive concern.
However, I would appreciate it
if you could be aware of the points above in ① advance.
Q10. I am new to skiing. How quickly can I expect to improve?
Progress varies depending on past sports experience and lower-body flexibility,
but based on my experience teaching at SNOVA, the following is a general
guideline
(assuming 60 minutes per lesson):
For complete beginners:
[First two lessons]: recommended "2-hour lesson package": ¥10,000/person
Lesson content:
・Explanation of ski equipment and how to handle it
(putting on and taking off skis, and how to carry them safely etc.)
・Moving on snow (walking, changing direction, climbing
gentle slopes)
・Sliding straight downhill and stopping in the snowplow
position
・How to stand up safely after a fall
・Continuous snowplow turns from the top of SNOVA slope
(only if appropriate for your level)
＊Only a few people have been unable to achieve this
in their first two lesson with me. Hip flexibility is the key.
[Lessons 2∼4]:
You will be able to perform continuous turns while maintaining a plough
stance
(commonly called plough turns or snowplough turns).
[Lessons 6∼10]:
You will be able to perform continuous stem turns
(a combination of parallel and plough positions).
[Lessons 10∼16]:
Although some plough stance may remain, you will be able to perform
continuous turns
in a mostly parallel stance on gentle slopes.
＊These levels are achievable, but not guaranteed.
Q11. What is the key to improving your skiing?
Skiing is a sport in which you glide down a slope
by using gravity as your driving force.
You must control your skis while allowing your body to move downhill
at nearly the same speed as your skis.
To achieve this, the following basics are essential.
More specifically, the key lies in the position of your ski boots.
I explain this clearly on the snow during the lesson.
Always stand perpendicular to the slope, keeping your center of mass positioned directly above your ankle joints.
While maintaining point 1, control your body position so that you can apply pressure to the outside (downhill) ski during the turn—the so-called “outside ski pressure.”
Unfortunately, many skiers are unable to fully control their skis.
In fact, during turns, they often end up being carried by the skis
rather than actively steering them.
Q12. What is the key to mastering parallel turns?
First and foremost, the two fundamentals mentioned in Q11 must be achieved to a considerable degree. Only then can you move on to parallel turns.
In a snowplow turn, your center of mass remains between the two skis forming a triangular stance, allowing stable control at low speeds.
In contrast, a parallel stance requires you to use the centrifugal force generated at higher turning speeds and shift your center of mass appropriately to control the skis throughout each phase of the turn.
The transition from one turn to the next is especially important. Many skiers fail to eliminate the snowplow stance during this transition.
In my lessons, as mentioned earlier, I first explain the mechanics of
the parallel turn
in detail with skis off, and then have students simulate the movement
to feel it in their bodies.
I believe that understanding through this simulation is essential
for efficiently learning parallel turns.
Sadly, many skiers end their skiing life without ever mastering the parallel
turn.
My goal is to help you break free from that pattern.
Q16. What are the characteristics of the slopes at "SNOVA Shin-Yokohama"?
It is Japan’s only fully enclosed, indoor ski slope open year-round.
The indoor temperature is kept near -3°C throughout the year.
There is also an indoor ski area in Tokorozawa (Saitama), but it is not open year-round.
At Snova, there is no lift, but a rubber-belt escalator takes you up the slope.
You must remove your skis when using it.
The slope is about 30 m wide and 60 m long.
The gradient is about 10° at the bottom and 14° at the top.
If you can ski continuous plough turns from the top of SNOVA’s slope,
you will generally be able to manage beginner or lower-intermediate slopes at regular ski resorts
(although falls cannot be completely ruled out).
Typical beginner slopes in ski resorts: 5–10°
Typical intermediate slopes in ski resorts: 15–20°
Rental equipment includes skis, poles, helmets, wear, and gloves.
Quantities are limited, but SNOVA gives priority to lesson participants,
which is why I ask for your sizes in advance.
Some items such as socks are also available for purchase.
For details, please contact SNOVA directly.
